PRESS-BUTTON.

Specification of Letters Patent.

Patented July 7, 1914.

Application filed March 16, 1912. Serial No. 684,217.

To all whom it may concern Be it known that we, JosEPH BOREL and FRANgoIs GRANGE, citizens of the Republic of France, both residing at Annecy, Haute- Savoie, France, have invented certain new and useful Improvements in Press-Buttons, of which the following is a specification.

This invention relates to a press button, the closing of which is effected by means of a spring penetrating into the male portion of the button after being moved away by simple pressure, the opening being effected by acting on the spring in a given direction. The button comprises, in addition to the general combination of its elements, means for securing the cap of cardboard or other material, a new shape of spring, means for attaching the spring to the base of the eyelet socket, and a special form of the eyelet socket itself, which is made in one piece.

The various parts forming the button, are illustrated in the accompanying drawing in which,

Figure 1 is a section of the cap made of cardboard or other material, Fig. 2 is a plan thereof, Fig. 3 shows the nipple or the counter-rivet, Fig. 4 is a sectional view thereof, F ig, 5 shows a widened eyelet in elevation, Fig. 6 is a plan thereof, Fig. 7 shows the eyelet-socket in plan and Fig. 8 in elevation, Fig. 9 shows the shape of the spring alone, and Fig. 10 the same in position and secured to the base of the eyelet-socket, the lugs of which, projecting in Fig. 7 have been folded over by the fixing of the spring, Fig. 11 is a sectional view of the eyeletsocket provided with the spring, Fig. 12 shows a second form of spring, Fig, 13 is a general view, in section, of a mounted button, Fig. 14 shows in elevation and Fig. 15 in plan the male part which penetrates into the button.

The button comprises: a cap 1, Fig. 1, of cardboard, corozo, bone, ivory, covered with celluloid or the like, or not and provided in the interior with two recesses 2, 3 of suitable shape. The recess 2 receives the nipple or counter rivet 4, Figs. 3 and 4, which is slightly flared upwardly, or undercut, and has a conical crown 4. When the said nipple has been put in place, the widened eyelet 5, Figs. 5 and 6, is introduced into the recesses 3 of the cap 1 and when pushed as far as it will go, will be securely retained in place, and at the same time will secure the eyelet 4.- in its recess 2. The widened eyelet 5 is provided with two or more small claws 6 the object of which is to keep the button in an existing button-hole in the leather or fabric to which the button is secured, or to penetrate into the leather of the boot or of the glove, the proper holding of the button thus being assisted. The widened eyelet 5 is introduced into its recesses 3 after it has been introduced into the perforations of the leather of the boot or of the glove for which it is intended, the attachment of the button to the leather being therefore effected during that operation, and the leather maintained thus between the bottom edge of the cap 1 and the base of the widened eyelet 5.

The part 7, Fig. 7, called the eyelet-socket, is stamped out of one piece and comprises a base 9 provided with four small lugs 10, ll intended to be folded over for securing and stopping the spring, and a hollow cylindrical part, the cage or socket, provided with a slot 12 for the passage of the spring,

and with a reduced upper portion, also hol-v low, which is crushed by setting or riveting in the nipple 4 the conical crown 4 facilitating this operation. The object of the undercut eyelet 4 is to prevent the riveting or spreading outward of the top of the socket 7 from splitting the head 1. In addition to the securing of the spring, the lugs 10 11 of the base of the eyelet-socket serve another object as they enable the workmen to leave to the spring just the play required for its satisfactory operation this being done readily merely owing to the thickness of the said parts 10 and 11 which, when coming to rest, during the riveting of the part, against the base of the widened eyelet '5, limit the said space automatically.

The spring 8, Figs. 9 and 10, is secured at one end to one of the parts 10 wound about the same, the other parts 10, 11 when once folded over as shown in Figs. 10 and 11, are used for limiting the travel of the spring during the opening, as shown dotted in Fig. 9.

The eyelet-socket is provided at its lower portion with a slot 12 intended for the passage of the spring 8 which thus penetrates into the recess 14 of the head 13 of the male part of the button (Figs. 14 and 15) when the latter part is introduced into the recess of the eyelet socket 7. The eyelet-socket 7 provided with its spring 8, mounted in the manner just described, is introduced into the cap 1 already fitted with the parts 4 and 8,

terminates also in a small ball.

- fingers on the said balls, in order to open the button and release the head 13 of the spring 8..

The operation of the button will be readily understood from the following: The button is mounted so as to surround the leather or fabric of the boot or of the glove as shown in Fig. 18. The male part of the said button is also mounted on leather, fabric, etc. When it is desired to close the button the male part 13 is forced to enter the inner recess of the female part, the spring 8 of which, once mounted occupies the position shown in Fig. 10, and penetrates to a certain extent through the slot 12 into the socket or recess of the eyelet-socket 7. The head of the button 13, on penetrating into the said recess, presses against the spring 8 which yields'and moves away following the convex shape of the head of the male part 13, then moves into the recess 14: and thus firmly secures the two parts together. For opening, it will be only necessary to move the spring 8 in a suitable direction by means of the small ball which terminates it, and to move away the male part thus released, whereupon the opening takes place.

It will be noticed that when the spring is operated to withdraw it from the socket, the legs of the U-bend approach each other. In other constructions of hand-operated springs for press-buttons, the U-bend was so arranged that the two legs were bent apart when operated to release the button, thus progressively weakening the spring. The spring according to the present invention is therefore much more durable than those hitherto used.

The spring is made of wire, the cap of the 7 button is generally made of compressed and adapted to enter the central recess, a retaining eyelet adapted to be forced into the annular recess and to retain the central nipple, a socket adapted to contain a handoperated spring, and having a cylindrical upper part adapted to enter the central nipple, to engage the conical crown thereof, and to' be spread or flanged outwardly thereby, whereby said socket is securely fixed to the cap.

2. In a press button, a cap having a central recess surrounded by an annular recess, an undercut nipple havlngaconlcal crown and adapted to enter thecentral recess, a' re-f taining eyelet adapted to be forced into-the. annular recess'and to retain the'central ni "j ple, a socket rovided with a slot and having? upper part adapted to be spread outward and be secured within the a cylindrica central nipple by means of the conicalcrown thereof, a flange extendin the lower edge of said socket, lugs on said flange, a spring having a U-bend, secured. and retained on said flange by said lugs and protruding through the slot in the socket, a protruding finger piece on said spring, and

laterally from I said spring being sosecured that when the finger piece is operated to withdraw the spring from the slot, the two arms of the U- bend are moved together.

In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
